Description

LAUNDRY WASHING APPARATUS PROVIDED WITH CLEANING
DEVICE
BACKGROUND
Technical Field
The present invention relates to a laundry washing apparatus provided with a cleaning device, and in particular, to a water pipeline of the laundry washing apparatus.
Related Art
An existing drum washing machine generally includes a rotary drum for accommodating laundry, a water tub arranged around the rotary drum, and a motor for driving the rotary drum to rotate. The rotary drum is provided with a sidewall approximately in a cylinder shape and an end wall at one end of the sidewall.
For the purpose of environmental protection and water saving, a water level for rinsing is generally designed relatively low; especially, when there is not much laundry to wash, the water level is even less than 1/3 of the diameter of a mounting bracket. Therefore, after the rinsing, an outer side of the end wall of the rotary drum and an inner wall of the water tub opposite to the outer side are adhered with half-dissolved washing powder that is splashed during the washing process, and dirt and fluff left after breaking of bubbles, which cause secondary pollution to the laundry to be washed subsequently.
An existing laundry drying apparatus, such as a laundry dryer or a washer-dryer with combining functions of laundry-washing and laundry-drying, generally includes a condensation device connected to the water tub, so as to condense moisture carried in drying air that enters the condensation device from the water tub and finally returns to the water tub.
Since it is unavoidable that a lot of fluff or other impurities (collectively referred to as fluff hereinbelow) are produced during the laundry-washing or laundry-drying process, the fluff may be carried directly into the condensation device with the humid and hot air and adhered to the inner wall of the condensation device, thereby affecting the condensation effect or obstructing the whole air circulation passage; even, the fluff may be carried into a fan or a heating tube by means of the fan and then adhered to a surface of the fan or the heating tube, thereby causing greater danger.
SUMMARY
An objective of the present invention is to enable a laundry washing apparatus to more effectively clean its own parts that need cleaning.
For the foregoing objective, the present invention uses the following technical solution: A laundry washing apparatus provided with a cleaning device includes a liquid containing tub, a rotary drum that is rotatably supported in the liquid containing tub, a treatment agent distribution box that is connected to the liquid containing tub to deliver a liquid mixture of water and detergent or water and other laundry care agent to the liquid containing tub, a first water pipeline for delivering water to the treatment agent distribution box, and a first water valve arranged on the first water pipeline, where the first water valve is connected to a control device and is controlled by the control device to open or close the first water pipeline that is communicated with the treatment agent distribution box. The first water pipeline between the treatment agent distribution box and the first water valve is arranged with a second water valve, where the second water valve is further connected to a second water pipeline, and an exit of the second water pipeline is arranged on or adjacent to a component to be washed. Large-flow and high-speed water is usually delivered to the treatment agent distribution box, which facilitates the flushing of the treatment agent that is added to the treatment agent distribution box in advance. Therefore, when such a water flow is introduced by the second water valve to the component to be washed, a preferable flushing effect is achieved, and dirt and/or fluff adhered to the component to be washed can be effectively flushed away.
As a possible improvement to the foregoing technical solution, the second water valve is connected to the control device, and is controlled by the control device to deliver water to either the first water pipeline or the second water pipeline.
Another possible improvement solution is as follows: The second water valve is controlled in such a manner so that the second water valve delivers water to the first water pipeline during a laundry-washing process and delivers water to the second water pipeline during a component-washing process. In order to clean an inner side of an end wall of the liquid containing tub and/or an outer side of an end wall of the rotary drum opposite to the inner side, an exit of the second water pipeline is arranged on a rear end wall of the liquid containing tub.
A more preferable improvement is as follows: The component to be washed is an end wall of the rotary drum, and the exit of the second water pipeline faces the end wall of the rotary drum; in this way, water that flows out of the second water pipeline may flush the end wall of the rotary drum, and the splash may further flush the inner side of the end wall of the liquid containing tub opposite to the end wall of the rotary drum.
The component to be washed may also be a condensation device connected to the liquid containing tub. The large-flow and high-speed water gushes out, which can effectively flush away the fluff adhered to the inner wall and components of the condensation device.
What is more beneficial is that, the exit of the second water pipeline is arranged close to an upper side of the condensation device.
For example the laundry washing apparatus is a washer-dryer with combining functions of laundry-washing and laundry-drying. Such a washer-dryer generally includes a condensation device connected to the water tub, so as to condense moisture carried in drying air that enters the condensation device from the water tub and finally returns to the water tub.
